DAGGER.

Specification of Letters Patent.

Patented May 2, 1916.

Application led. February 21,1913. Serial No. 749,920.

To all whom it may concern.' l

Be it known that I, EDOUARD-PIERRE NICAUD, citizen of the Republic ofFrance, residing at 5 Rue Lamartine, Blida, Algeria, have invented newand useful Improvements in Daggers, of which the following is a.specification. v

This invention relates to daggers or similar pointed weapons and has forits object an improved arm of this kind particularly intended for use asan arm of defense, the main feature thereof being that the sheath whichnormally covers the blade is automatically retracted into the handlewhen stabbing. The advantage thereof is that the person provided withthe improved dagger, if suddenly attacked, can protect himselfinstinctively with his left arm and draw the dagger from his pocket withhis right hand, the dagger being immediately ready for use, withouthaving the trouble of removing any sheath from the same, which usuallyrequires both hands and a certain time.

In the annexed drawing given by way of example: Figure l is a side viewof the improved dagger, in its normal condition when carried in thepocket. Fig. 2 is a corresponding side View of the dagger in positionwhen stabbing. Figs. 3 and t are longitudinal sections correspondingrespectively to Figs. l and 2. Fig. 5 is a cross section along the lineA-A, Fig. il.'

The dagger shown by way of example has a steel blade a of a cylindricalform and pointed at one end. The opposite end of the blade is screwedinto a cap b which is to be secured on one end of the tubular handle oof the weapon. The cap may be internally threaded to be screwed onto thethreaded end of the handle as shown. The opposite end of the handle c isclosed by a wall Z having an opening 7". It is also surrounded by anannular shield or guard g formed'by a ring having an L cross sectionscrewed or otherwise secured on the end of the handle. In the handle, ismounted the sheath 7L comprising a metal tube which can slide throughthe opening f of the handle and is closed at one end by a wall z'provided with a small opening through which the blade can extend. At itsopposite end, the sheath h is provided with an outer cylindrical flangej which is guided in the handle. In the sheath 7i is located a helicalspring 7c which surrounds the blade a and bears at one end against thewall z' of the sheath and, at the other end, against the cap Y) so thatthe sheath is normally pushed outwardly over the blade, the flange jabutting against the end wall fl of the handle.

The dagger thus constructed can be carried in the pocket without beingplaced in an outer sheath as the blade is entirely hidden in the tubularsheath 7L. When the dagger is grasped by means of the handle and a blowis given therewith, the sheath is ar rested by the body against whichthe blow is struck while the blade penetrates into the same, the sheath7L retracting into the handle. lVhen the dagger is withdrawn the sheathIt protrudes again over the blade under the action of the spring 7c.

The blade may obviously have any other form or section.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is:

A dagger comprising a handle; a bla-dc secured to the handle; a sheathof smaller diameter than said handle and adapted to be retracted intothe handle or protruded over the blade, and having an interior flange atits outer end; and a spring arranged around the blade within said handleand sheath, and bearing at one end against the upper end of the handleand at the other end against the said flange of the lower end of thesheath.

In testimony whereof I have signed. my name to this specification in thepresence of two subscribing witnesses.
